NASA: Navigation failure caused the mission of the "Wit" Mars helicopter to end. NASA said on December 11 that the investigation and evaluation of the "Wit" Mars helicopter showed that the navigation system failure was the cause of the rotor damage and the end of the mission during its landing. The "Wit" helicopter landed on Mars with the American "Perseverance" rover on February 18th, 2021. It weighs about 1.8 kilograms, has four rotors, and is powered by solar panels for lithium batteries. On April 19th of the same year, Wit completed its first flight on Mars. On January 18th this year, Wit made its 72nd and last flight to Mars. Because its rotor blades were damaged during the landing, it could not fly again, and NASA announced the end of its mission. On the 11th, NASA announced the investigation results of the last flight of Wit. The evaluation shows that the navigation system of "Wit" can't provide accurate data during its flight, causing a series of failures, leading to the end of its mission.

On the morning of December 12, local time, South Korean President Yin Xiyue made another televised speech, refused to step down early, and denied that martial law was a crime of civil strife. After Yin Xiyue's speech, public opinion in South Korea immediately criticized him. South Korea's largest opposition party, the Common Democratic Party, said that Yin Xiyue was mentally ill and called on the South Korean National Assembly to pass the impeachment case. After Yin Xiyue's speech, Han Dongxun, the representative of the ruling party in South Korea, also said that Yin Xiyue's speech had no introspection and was rationalizing his behavior. Some commentators pointed out that Yin Xiyue may have expected that he could not prevent the National Assembly from passing the impeachment case and was trying to influence the final ruling of the Constitutional Court. I am afraid that the chaos in Korean politics will continue.

Intel: Breakthrough progress has been made in chip interconnection, and the inter-line capacitance has been reduced by 25%. Recently, Intel OEM announced a major breakthrough in on-chip interconnection technology. The latest subtractive Ruthenium interconnection technology of the company can reduce the inter-line capacitance by up to 25%, effectively improving the on-chip interconnection. According to reports, the subtractive ruthenium interconnection technology has achieved great progress in interconnection miniaturization by using ruthenium, a new, key and alternative metallization material, and using thin film resistivity and airgap. This process does not need an expensive photolithographic air gap exclusion zone around the via, and it can also avoid using a self-aligned via that is selectively etched. When the spacing is less than or equal to 25 nm, the air gap realized by reducing ruthenium interconnection technology can reduce the capacitance between lines by up to 25%, which can be used as a metallization scheme to replace copper damascene process in closely spaced layers. It is reported that this solution is expected to be applied in the future process nodes of Intel OEM.

The Notice makes it clear that from December 15th, 2024, all workers who participate in the basic old-age insurance for urban workers or urban and rural residents in China can participate in the personal pension system. The Circular stipulates that on the basis of existing wealth management products, savings deposits, commercial old-age insurance and Public Offering of Fund products, national debt, specific old-age savings and index funds will be included in the scope of personal pension products. Encourage financial institutions to research and develop financial products such as personal pension savings, medium and low volatility or absolute income strategic fund products that meet the long-term pension needs, and reasonably determine the term and interest rate of personal pension savings. Financial institutions should do a good job in publicizing the asset allocation of personal pension products, carry out investment consulting services according to laws and regulations, and explore the default investment services. Strengthen the protection of financial consumers and investors, and guarantee the participants' right to know and choose independently.
